摘要

Windbreaks as part of the landscape structures influence the local wind field. To plan and analyze these windbreaks, it is necessary to precisely record the different landscape structures. The height and spatial arrangement of the landscape elements determine their wind protection effect, which was determined from a digital elevation model based on aircraft-based laser scanning. The ArcGIS toolbox ‘WERA’ allows a detailed analysis of the landscape structure on wind erosion processes. The presented method combines heights of LE and the directional transport capacities of erosive wind speeds to analyze the spatial wind speed reduction by windbreaks or other landscape elements. Combined with the soil-derived erodibility map, a wind erosion risk map can be derived. The analysis can be performed at the field, landscape, or regional level. This is an important planning tool for windbreaks to minimize wind erosion and evapotranspiration.
